The Demons and Angels War

Not much is known about this time period, but it is assumed to have taken place from about 2 years before season 1, after the massacre of Demon Squad, and the end of season 2 when the Angels are nearly abolished. Indiana would apparently frequently send out his few soldiers to go pick off Angels whenever they could. This was pretty much an uphill battle for Demon Squad, seeing they were extremely outnumbered. The only thing that kept Nathaniel from instantly striking Demon Base (until Season 2 Episode 9) was his conflict with Indiana. His desire for a friendship with Indiana held back the war for about 2 years.
 * Started: Demon Base, 2 years before Season 1 due to the murder of Demon Squad
 * Ended: The Battle of Angel Fortress, end of Season 2
